Detailed Explanation of Sprinkler Irrigation Techniques for Soybeans During the Pod-Filling Stage
When soybeans enter the pod-filling and maturation stages, they still need some water and nutrients to promote material accumulation and maturation, improve the seed-setting rate, and increase yield. For many years, when soybeans enter the pod-filling stage, conditions are generally very dry, which adversely affects the pod filling and maturation of the top and upper pods. In response, some farmers use sprinkler irrigation with well water during this period to alleviate the drought. Production practice has proven that soybeans sprinkler-irrigated with pumped water during the pod-filling stage not only fail to promote maturation after one week, but instead cause some branches and plants to turn yellow prematurely or even die, thereby reducing yield. The reason is that soybeans

Cotton drip irrigation automation project boosts yields
The Shihezi "Cotton Drip Irrigation Automatic Control Science and Technology Demonstration Project", which has been included in the national plan, will add another 15,000 mu to its experimental demonstration area this year on top of last year's. In recent years, after the Shihezi reclamation area vigorously promoted and applied cotton under-mulch drip irrigation technology, total cotton output and per-unit yield have increased substantially. **Tianye Group Corporation, as the largest domestic producer of agricultural water-saving drip irrigation equipment, has promoted water-saving drip irrigation over more than ten million mu. In order to seize the scientific and technological high ground, the company independently innovated and developed the "Cotton Drip Irrigation Automation

Detailed Explanation of Key Points of Scientific Irrigation Technology for Cotton
Cotton is a taproot crop, with the main root penetrating relatively deep into the soil, making it a relatively drought-tolerant crop. The period from squaring to boll opening is the critical period for water demand. 1. Conventional irrigation: Irrigate 3-4 times throughout the growth period. The first irrigation is at the squaring stage, i.e., mid-to-late June; the second irrigation is at the full flowering stage, i.e., mid-July; the third is at the flowering and boll-setting stage, i.e., from late July to early August; by the initial boll-opening stage, if the weather is dry or the soil is sandy and prone to leakage, one more irrigation may be applied. If there is abundant rainfall and no sign of drought, watering may be discontinued. Apart from 120 cubic meters per mu for the pre-planting water, the irrigation quota for each application during the growth period is 6

Detailed Explanation of Agronomic Supporting Techniques for Drip Irrigation Under Plastic Mulch in Cotton
Drip irrigation under plastic mulch is a technique that combines drip irrigation technology with plastic film mulching cultivation technology. Water is supplied through a controllable pipeline system; after water and fertilizer are mixed, they are delivered drop by drop evenly, at set times and in set amounts, moistening the crop root development zone and always keeping the root-zone soil loose and at optimal moisture. It reduces evaporation between crops and improves water use efficiency. 1. Irrigation regime. For subsurface drip irrigation, total water use was 175.48 million cubic meters. Dripping was done 9 times. For precision drip irrigation, total water use was 177.84 million cubic meters. Dripping

Detailed Explanation of Key Points of Cotton Cultivation Technology with Drip Irrigation under Plastic Film
I. Pre-sowing Preparation 1. Variety Selection: According to climate and soil conditions, select varieties with a growth period of about 130 days, resistance to Fusarium and Verticillium wilt; compact plant type, short fruiting branches type I~II, small insertion angle; moderate to small leaves, short petioles, not prone to vegetative branches; strong boll setting, and good fiber quality. Such as 9665, JD~3, Fengmian No. 8, Jiumian No. 2, etc. 2. Deep Application of Base Fertilizer: The amount of chemical fertilizer is 8~12 kg of pure nitrogen, 7~10 kg of phosphorus pentoxide, and 3.5 kg of potassium oxide. When deep plowing to kill stubble, apply farmyard manure

Detailed Explanation of Key Technical Points for Drip Irrigation and Fertigation under Cotton Mulch
Drip irrigation under cotton mulch is a new water-saving technology that allows artificial control of irrigation volume and field microclimate, greatly alleviating the **tension of water use for the first irrigation, and can control the reproductive growth and vegetative growth of cotton, helping to shape an ideal plant architecture and reduce ineffective nutrient consumption. Although some problems still exist in practical application, cotton under drip irrigation generally opens bolls earlier, has better quality and higher yield. At the same time, under special climatic conditions, drip irrigation has demonstrated unique cold resistance. When encountering special low-temperature conditions in spring and autumn, growth and development remain normal, with strong high and stable yield, and a relatively concentrated maturity period.

Key Technical Points for Cultivation and Management of Cotton under Hose Drip Irrigation
As the crop area in Jimsar County has increased year by year, water resources have become scarce, and the cost of cotton has risen, the comparative benefit of cotton has declined year by year. For this reason, we introduced and promoted the technique of cotton drip irrigation under film at normal pressure (hose). I. Main indicators 1. Yield: 100-130 kg of lint cotton per 667 sq m. Yield composition: 13,000-15,000 harvested plants per 667 sq m, 5-6 bolls per plant, 5 g per boll, lint percentage 33%-35%. 2. Fertilizer and water

Analysis of Key Technologies and Economic Benefits of Deep-Buried Drip Irrigation for Cotton
Cotton "deep-buried" drip irrigation technology is another new high-efficiency water-use technology that has emerged following cotton subsurface hose micro-porous irrigation technology. This technology can utilize fertilizer and water with high efficiency, and its yield-increasing effect is obvious. I. Key Technologies 1. Irrigation The start of irrigation is at the cotton squaring stage. In the cotton region of northern Xinjiang, this is generally June 7-10, with irrigation carried out on a 3-day rotation cycle. If autumn is rainy, irrigation can be carried out on a 5-day cycle. Irrigation amount: at the squaring stage, each irrigation is 8 cubic meters per 667 sq m; at full flowering, 10 cubic

Occurrence Patterns and Control Methods of Cotton Pests under Drip Irrigation
With the large-scale application of drip irrigation technology for cotton, the irrigation method has been improved. It delivers water and nutrients evenly and continuously to the vicinity of the cotton root system at scheduled times and specific locations, and the supporting cotton cultivation techniques have changed accordingly, causing corresponding changes in the ecological environment of cotton field pests and their occurrence patterns. For this reason, it is highly necessary to clearly understand the occurrence patterns of cotton pests and the technical control measures under mulched drip irrigation, so as to ensure sustained and balanced increases in cotton yield. 1. Cotton bollworm 1. Occurrence level Compared with previous years, the occurrence in 2005 was moderate to severe
